## Why update_tag is rated Medium

The tool updates tag metadata, which is a Write operation (modification of data). The blast radius is low because tag updates affect only metadata organization and do not impact financial systems, execute arbitrary code, or destroy data. The change is reversible via subsequent updates.

From the tool's own definition: "Tool name is 'update_tag' and description states 'Update a tag's details' — this modifies existing data (a tag) reversibly without deletion or irreversible effects."

## Use case

AI agents use update_tag to create or update resources in Mealie MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mealie MCP Server environment.
